"'One Pound Fish' enters the Official UK Top 40 today at no. 29! Amazing achievement. Many congrats to Shahid and thanks to Reggie Yates for having us on Radio 1 for the chart show," said the singer's publicist Samir Ahmed.

Former market trader Muhammad Shahid Nazir shot to fame after a video of him selling fish went viral, with his catchphrase call out: "Come on ladies/Come on ladies/One pound fish."

The X Factor contestant performed the single on Saturday (December 22) at West Ham's Upton Park stadium.
